Free Measurements 02 Practice Test - 5th Grade 

Question 1

Select the option in which the measurement conversion is correct. 

A.

1 m = 100 mm

B.

1 km = 100 m

C.

1 m = 100 cm 

D.

1 cm = 100 mm

SOLUTION

Solution : C

We know that,
1 m = 100 cm
1 km = 1000 m
1 cm = 10 mm
∴ In the 4 given options, 1 m = 100 cm is correct.

Question 2

1 L = ____ mL

 

A.

10 mL

B.

100 mL

C.

1000 mL

D.

10000 mL

SOLUTION

Solution : C

When we convert a larger unit (L) to a smaller unit (mL), we multiply by the conversion factor.

Hence, 1 L = 1×1000 = 1000 mL

Question 3

The milk in a spoon is approximately

A.

5 mm

B.

5 cm 

C.

5 mL

D.

5 L

SOLUTION

Solution : C

We know that spoon is a small object which can hold very little quantity of liquid. 

Here, millimetre (mm) and centimetre (cm) are the units of length.

A litre is used to measure a large quantity of liquid.

Therefore, milk in a spoon is approximately 5 mL.

Question 4

Long distances between two places are measured in _____.

A.

Millimetre

B.

Milligram

C.

Kilometre

D.

Kilogram

SOLUTION

Solution : C

Kilogram (kg) and milligram (mg) are the units of mass.

Millimetre (mm) is the unit used to measure the length of very small objects like the length of a pin, seed etc. 

Kilometre (km) is the unit used to measure long distances between two places.

Question 5

By how much is the length of string A more than string B?

A.

10 mm

B.

20 mm

C.

30 mm

D.

40 mm

SOLUTION

Solution : A

String `A` is starting from 1 cm.
∴ Subtract 1 cm from 9 cm.
Lenght of string A
=9 cm−1 cm=8 cm

String `B` is starting from 3 cm.
∴ Subtract 3 cm from 10 cm.
Length of string B
=10 cm−3 cm=7 cm

Thus, the difference in length of  String `A` and String `B`
=8 cm−7 cm=1 cm=10 mm

∴ The length of string A is more than string B by 10 mm.

Question 6

Find the missing quantity:

1 L = 350 mL + ______ mL

 

A.

600

B.

650

C.

700

D.

750

SOLUTION

Solution : B

We know that, 
1 Litre = 1000 mL

We already have 350 mL,
⇒ 1000 mL - 350 mL = 650 mL

∴ 1000 mL = 350 mL + 650 mL

Question 7

8 hectometres =_______ metres.

A.

8 

B.

80 

C.

800 

D.

8000

SOLUTION

Solution : C

When we convert a larger unit (hectometre) to a smaller unit (metres) we multiply by the conversion factor.

1 hectometre = 100 m

Hence 8 hectometres = 8 × 100 = 800 m

Question 8

Tina went to a shop to buy 3 litres of orange juice for a party. The store sold orange juice only in 250 mL cartons. How many 250 mL cartons will Tina need to buy?

A.

4

B.

8

C.

16

D.

12

SOLUTION

Solution : D

     1 L=1000 mL
⇒3 L=3×1000 mL
            =3000 mL

Therefore, the quantity of juice Tina wants to buy equals 3000 mL.

Since the store sells only 250 mL cartons, the number of such cartons that Tina has to buy is given by 3000250=12.

Question 9

An ant goes 3 cm forward then goes 2 cm backwards and then finally 5 cm forward. What is the final position of the ant if the initial position of the ant is shown on the scale? 

A.

6 cm

B.

7 cm

C.

8 cm

D.

9 cm

SOLUTION

Solution : C

Initial position of the ant = 2 cm

Ant goes  3 cm forward = 2 cm + 3 cm = 5 cm

Ant goes 2 cm backward = 5 cm - 2 cm = 3 cm

Finally, the ant goes 5 cm forward = 3 cm + 5 cm = 8 cm

∴ The final position of the ant is 8 cm

Question 10

From the given figure, find the weight of the mangoes.

A.

2 kg

B.

2.4 kg

C.

2.8 kg

D.

3 kg

SOLUTION

Solution : B

Weight of mangoes + 100 g + 500 g = 1 kg + 2 kg
⇒Required weight + 600 g =3 kg
⇒Required weight=3 kg - 600 g

To move ahead, we need to convert the units. Since we need the final answer in kilograms, let us convert 600 g to kilograms.
        1 kg=1000 g
⇒ 600 g=6001000 kg
                =0.6 kg
∴ Weight of mangoes =3 kg - 0.6 kg
                                        =2.4 kg
